We are pleased to introduce our latest celebration of menstrual cycles — The Periodic Table of Your Period. An illustrated guide to all things menses, we have included everything from bloating to chocolate, corpus luteum to period underwear. My geochemist husband came up with the idea and of course I am always dying to draw happy tampons, fallopian tubes and mucous, so I finally got my chance! If you look closely, you’ll find smiling condoms, IUDs and diaphragms in the Birth Control Series, alongside chemical diagrams of progesterone, folic acid and other important substances that course through your veins monthly.

The categories are conveniently color-coded and the whole thing is downloadable in case you want to frame it for your powder room. -via Laughing Squid
